An ant of negligible dimensions starts at the origin (0,0) of the standard twodimensional
rectangular coordinate system. The ant walks one unit right, then onehalf
unit up, then
1/4 unit left, then 1/8 unit down, etc. In each move, it always turns counterclockwise
at
a 90 degree angle and goes half the distance it went on the previous move. Which point
(x,y) in the xyplane
is the ant approaching in its spiraling journey?

f(x) = -x^2 + 9
g(x) = 2x^2 + 5x - 3
a) (g-f)(x) pretty sure the answer would be 3x^2 + 5x-12
b) f(g(x)) not really sure on if you would do the negative first or square it first and then take the negative
c) (f/g)(x) pretty sure the answer would be (-x+3)/ (2x-1)

For all positive integers n, the symbol n! denotes the product of the first n positive
integers.
Example: 4! = 4x3x2x1=24
Find the value of n for which (3!)(5!)(7!) = n!

How do the humans travel from planet to planet. They must
be traveling faster than the speed of light because some of the planets are 19 light years away and yet the travel time is a month. What propulsion system do they use? If it is faster than the speed of light, then how do they reconcile the time dilation which Einstein's theory of relativity describes? The three Legend books from Dune happen at a time before the ability to fold space so I'm just wondering how they are able to travel so fast (and without the use of computers!).

Ok- I always see in these prison related scenes from movies and tv about inmates putting ground glass in food, or being afraid of eating ground glass.

What actually happens when you swallow ground glass? I mean, is it just painful? or is it something that would kill you? Or is this just a myth?

I've come to the conclusion that if a rotating black was rotating at once per second then its maximum dia..must not exceed 59271.5454545455 miles. otherwise its suface at the equator would be traveling faster than light.
Is this true..
